Hello my name is Pedro I have a problem. Every time i tried to animate a assambly using animation, not a motor, for moving the parts i have a big trouble. For some reason all the assambly separtes and all the parts start to move everywhere on the screen. I have a video so you can see the problem (I tried to soled it even tough i follow all the steps from a tutorial three times). Thanks for any help i will be glad.

Yes this is the file. I uploaded in a Zip file. Please if this had happend to any of you and solve that problem please let me know( the assambly in the video has all constrains since is the file from a tutorial).

Hello. Thanks for all the help. I just follow step by step the instruction in this video Unit 4: Simulation - Lesson 1: Motion Study - YouTube . With the motor i have no problem but with the animation (the first part of the video basically) the problem it is shown. I check to see if something in the program was installed not in the rigth maner, but i couldn´t find mistakes.

Thanks for the help anyway, I am a beginner in CAD software so I am going to be using continuosly the forum.
